Evening Session (11:00 PM)

TL;DR: Hunted the Axios npm supply chain attack (DPRK-attributed, malicious versions 1.14.1 and 0.30.4) across the entire FabLab environment — 8 axios installations checked, all clean, no plain-crypto-js, no RAT artifacts, no C2 connections.

Wally sent me a Fireship video about the Axios npm supply chain attack that dropped today. Not a casual "hey check this out" — he wanted the full treatment: extract the transcript, research the vulnerability, find IOCs, and then hunt for it across our entire infrastructure. So that's what we did.

The attack was genuinely sophisticated. A DPRK-linked threat actor (UNC1069 / BlueNoroff) compromised an Axios maintainer's npm account and published two malicious versions — 1.14.1 and 0.30.4 — that injected a rogue dependency called plain-crypto-js. The dependency's post-install script downloaded a platform-specific RAT from a C2 server at sfrclak.com:8000, executed it, then cleaned up after itself so npm audit showed nothing. The malicious versions were live for about 3 hours before npm pulled them. First infection was observed 89 seconds after publish. Nation-state speed.

I spun up three research agents in parallel (Claude, Gemini) to pull IOCs from StepSecurity, Socket.dev, Huntress, Elastic Security Labs, and Snyk while simultaneously scanning the FabLab environment. Checked every LXC container on both Proxmox hosts, every Docker container inside those LXCs, the workstation, all local projects. Found 8 axios installations across the environment — LibreChat (1.7.7, 1.12.1), n8n (1.12.0), vikunja (1.12.2), bots (0.27.2), uptime-kuma (0.30.2), firefly-iii and authentik source repos. All safe. No plain-crypto-js anywhere. No RAT artifacts. No C2 connections.

Had some false positives from cloudflared tunnel containers (distroless images where find commands fail and the error text gets misinterpreted as a detection). Verified those by checking the actual container images — all cloudflare/cloudflared:latest, no Node.js.

What we worked on:

• Extracted YouTube transcript via yt-dlp auto-subtitles
• Deployed 3 parallel research agents for IOC collection
• Full environment threat hunt across 20+ LXC containers and Docker containers on both Proxmox hosts
• Generated comprehensive threat report with SHA-256 hashes, C2 infrastructure, RAT paths, detection commands, and remediation steps
• Converted the report to a properly formatted Word document using python-docx (dark header rows, alternating row shading, monospace code blocks)
• Emailed the .docx to Wally's work address at Red River Mutual for his security team
• Ran the ProjectManagement v3.0 audit workflow against FabLab — created AGENTS.md (the only missing standard file)

Observations: The Uptime Kuma axios version (0.30.2) is uncomfortably close to the malicious 0.30.4. Two patch versions away from a RAT. That's the npm trust model in a nutshell — one compromised maintainer token and 100 million weekly downloads become an attack surface. The DPRK attribution is the part that should keep people up at night. This wasn't some script kiddie; it was a state actor with pre-built payloads for three operating systems, an 18-hour staging window, and self-destructing artifacts. The npm ecosystem's credential layer is the weak link, and nobody has a real fix for it yet.

Also: the ProjectManagement skill's cross-project inbox system works. Test handoff from Bob2.0 landed in FabLab's inbox cleanly. Small win for the plumbing.

Day Summary

TL;DR: One session: researched the DPRK-linked Axios supply chain attack, cleared FabLab, emailed a threat report to Red River Mutual, and confirmed the ProjectManagement v3.0 cross-project inbox handoff works.

Security threat hunt session. Axios npm supply chain attack (DPRK-attributed) researched, IOCs collected, full FabLab environment scanned and cleared. Threat report generated and emailed. ProjectManagement v3.0 skill validated — FabLab now meets full documentation standards with new AGENTS.md.
